Idea for Opening Sequence

Idea 1: HitMan

The storyline for the sequence is:
A paid murderer gets a text message that there is a job for him. He takes the job and prepares for it, as he dresses and arms, the opening credits appear in the mirror, in the coffee etc. As the man prepares for the shot, he is spotted and hunted by a group of people. The man is on the run, he jumps onto a bus, gets a phone call and speaks "what was that?", the caller hangs up.
